W/LLHQD P NDOEF BY $5 2M ML ATTOEMEK United States Patent 3,342,369 ROOF SPRAY GUN KIT Willard Randorf, Beachwood, Ohio, assignor to Ranco Industrial Products Corporation, Cleveland, Ohio, a corporation of Ohio Filed Feb. 5, 1965, Ser. No. 430,711 2 Claims. (Ci. 2204) ABSTRACT OF THE DISCLOSURE A unitary container for components of liquid spraying equipment, including pump, gun and associated hose lines.

This invention relates to sheet material containers, and particularly to a unitary packaging kit. Conducive to a better understanding of the invention, it may be well to point out that both the fabrication and maintenance of so-called built-up felt roofs, for commercial and industrial buildings, requires the application of a bituminous sealing liquid.

Such sealing liquids are usually fairly viscous in nature, and must be hand brushed on to the roof surface, or sprayed on by means of special pumping equipment.

The latter method is preferred when large areas are to be treated, since it requires less labor and provides better and more uniform coverage.

The liquid bituminous material is normally packaged in 30 or SS-gallon steel drums, and in order to promote the sale of their product, many manufacturers loan the necessary pump, spray gun and associated hose connections, to purchasers, for use in applying their product.

Since such equipment is relatively expensive, costing in the neighborhood of $2,000.00 per unit, the problem of proper packaging for the delivery and return of the equipment is of some consequence.

Such an applicator unit usually comprises an air operated material pump, a pole spray gun, for applying the material, and approximately 450 feet of hose for the necessary connection between the material drum, pump, air gun, and the source of compressed air used to operate the pump and atomize the liquid spray.

The common practice is to package the equipment in a number of separate boxes and barrels. Careless workmen often neglect to return all the equipment or re-package it in an improper manner, leading to loss and deterioration of the equipment.

The primary object of this invention, therefore, is to provide a unitary compartmentalized, dual covered, packaging kit for a roof coating spray gun and its associated equipment.

Another object is to provide such a kit, having separate compartments for holding the air and material delivery hoses, so that any viscous material remaining in the fluid hoses will not contaminate the air hoses.

A further object is to provide a unitary kit that also provides space for the storage of the pump and pole gun, as well as the hoses, so that everything is completely protected from the elements when the package is closed.

Still another object is to provide a packaging kit whose interior is readily accessible for the removal and re-packing of its contents; that is rugged in construction; and that is relatively inexpensive to manufacture.

These, and other objects of the invention will become apparent from a reading of the following specification and claims, together with the accompanying drawing, wherein like parts are referred to and indicated by like reference numerals, and wherein:

FIGURE 1 is a perspective view of the unitary packaging kit that is the subject of this invention, showing it in its fully loaded and sealed condition; and,

3,342,369 Patented Sept. 19, 1967 FIGURE 2 is a vertical cross-section of same.

Referring more particularly to the drawing, there is seen in FIGURE 1 the Roof Spray Gun Kit that is the subject of this invention, broadly indicated by reference numeral 10.

In the preferred form, illustrated, the kit 10 is fabricated from two cylindrical steel drum sections 11 and 12.

The lower cylindrical section 11 has a capacity of 55 gallons, while the upper cylindrical section 12 has a capacity of 30 gallons.

Section 11 has a bottom wall 15 and a removable cover 13 that engages the top rim of section 11, and may be sealed and locked in place by a clamping ring 17 that is drawn up by a locking bolt 19.

Cylindrical section 12 has a bottom wall 16 and a removable cover 14 that may be locked in place by a clamping ring 18 that is drawn up by a locking bolt 20.

Section 12 is centered and permanently mounted on the top surface of cover 13, through a continuous weld seam 21.

The opposed surfaces of the cover 13 and bottom wall 16 define a partition between the interior compartments of sections 11 and 12, as is seen in FIGURE 2.

Reference numeral 22 indicates an opening through the partition which provides communication between the upper and lower compartments of the kit 10.

A circular platform 29 surrounds the opening 22 in the partition.

It will be seen that the cover 13 of the lower section 11 is of a piece with section 12, so that when the cover 13 is locked in place on the section 11, as is seen most clearly in FIGURE 2, the two cylindrical sections 11 and 12 are inseparable and form the unitary kit 10.

To load the kit 10 the locking ring 17 is loosened and removed. The cover 13 and its attached section 12 are then free to be lifted off lower section 11, and placed to one side on the ground.

Clamp ring 18 of the cover 14, of section 12, is then loosened, permitting removal of the cover from section 12.

Four 50-foot lengths of A material delivery hose 28, are then coiled against the inner wall of section 11. Four 50 foot lengths of /2" air hose 27, for delivery of material atomizing compressed air to the pole gun 25, are coiled upwardly from the platform 29, and against the inner wall of section 12. One 50 foot length of %1" air hose 30, for delivery of compressed air for the operation of the material pump 24, is coiled upon the platform 29, inside the coiled /2 hose 27, as seen in FIGURE 2.

The pump 24 and pole gun 25 are strapped together by means of straps 31, with a wooden spacer 26 therebetween, to form a compact unit which is inserted into the kit section 11, with its lower end resting on a wooden cushioning block 23.

Upper section 12 is then fitted over the pump-pole-gun package, which extends through the partition opening 22 into the interior of the section 12. The platform 29, surrounding the partition opening 22, acts as a center brace for the pump-pole-gun package.

At the same time the cover 13 is fitted over the upper rim of lower section 11 and locked in place by clamp ring 17.

The cover 14 is then mounted on section 12 and locked in place by its clamp ring 18.

It will be evident that the so assembled unit provides a compact and weather-tight packaging kit for the pump, pole-gun, and their associated operational hoses, that may be easily shipped with the assurance that none of the contained equipment will be lost or damaged.

To unpack the kit 10, the foregoing procedure is reversed.

While the upper section 12 has been illustrated as having a bottom wall 16, it is to be understood that this may be omitted and the bottom-less end of the section 12 welded directly to the cover 13, which, in that case, serves both as the bottom of section 12 and the cover of section 11.

It will now be clear that there has been provided a device which accomplishes the objectives heretofore set forth.

While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof, as described and illustrated herein, is not to be considered in a limiting sense, as there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claims.
